Error Codes

If an error occurs during API calling, no result is returned. You can locate the cause of the error according to the error code of each API.

If an error occurs during API calling, the returned message body contains the specific error code and error information. If you fail to locate the cause of an error, contact HUAWEI CLOUD service support and provide the error code so that we can help you solve the problem as soon as possible.

If an error code starting with APIGW is returned after you call an API, rectify the fault by referring to the instructions provided in API Gateway Error Codes.
